Griffin radiator and twin fans still running at 190-200?

Hi Guys,
I installed what griffin calls a direct fit aluminum radiator with the custom built aluminum shroud and 2 spal 10" fans. Came with 2 relays. So, I wired the two fans placing the ground wires for each fan in a different location. I then wired the fan supply to the red feeds from each relay. I wired the other heavy wire to the side accessory post on the optima battery and installed a 15amp fuse in each line. I then took the sending unit they included and had to bush it down with an aluminum bushing and installed it into a port in my edelbrock aluminum manifold. Then I insyalled the two sending unit wires to the post on the sending unit. I then checked for and found a 12volt source wire which is always live while the car is running. Now I also have an autometer temperature guage with its own sending unit in a different location on the manifold. It was always reading high when sitting in traffic. If I drove for a while it would drop to 180. It was sitting in traffic that seemed not so good. I thought the griffin radiator and twin fans would idle at the 180. So far, not so much. Fans appear to be kicking on at the guage reading about 200-210? I have only had the car idle so far, but the fans seem to drop the temp down to about 190 while idling. Hopefully it will drop more when driving. And it is not 90 degrees yet. My car is an a/c car so does have the newer thin condenser up front. Motor is a 416 stroker motor. I should also mention it appears to be running rather eye burning rich while idling? I did have it dyno tuned and the man rejetted the carb. Has a Holley 770 cfm double pumper. Holley told me to install a vacuum guage at the carb base and adjust the four corner metering to get the highest vacuum reading and see if it is just the idle circuit running to rich. They also told me I may want to open the automatic choke adjustment a bit to let more air in on startup. I don't know if this stuff would make the car run warm? Or maybe the autometer guage is off? I also am running the Evans coolant in the engine. Son't know if that plays games with the water temp sending units? Also, I did place some ARP liquid Teflon around the treads of the fan sending unit? Wondering if that is turning fans on too high? It is suppose to be turn on at 185 and of at 165? Turning on more like 200. Any thoughts on this would be helpful. I should also state that all this stuff is brand new.
